Scales Page
The tables below give an outline of the ranges that
apply to each of the four major scale formats. Players should note that while
each game scale has a recommended model scale associated with it, that is only
a recommendation. In reality any scale of model may be used with the various
formats so long as players are able to get a satisfactory effect for game play.
The first table is a list of scales and ranges, some of which are required
knowledge for game play, and others of which are for reference for setup or
general information. Note that within the rules text, ranges are offered
referred to in "cables." A cable is one-tenth of a nautical mile, and
within the rules text it is commonly used to define or control short range
distances. The tabletop range for "one cable" can be marked on the combat
chart, immediately beneath the Torpedo table.
The second set of tables
below are for calculating the scale game speed available to a ship. Included
are multipliers for calculating the basic game speed of a ship based on its
original maximum speed in knots. There are also six Increment
multipliers for calculating the six levels of a vessel's propulsion box
speeds for use in the ship logs. The multipliers for establishing the
Basic or maximum available speed of a vessel based on the real life
original speed are immediately below the Speed and Movement header. Below that
is a short list of of sample speeds and their related lists of speed
categories. At the bottom is a short fraction rounding guide to let players
know how best to round fractions for the inch based scales. Note that
destroyers and other very light craft use only three speed increments instead
of the usual six increments used for all larger vessels. |

¹ Multiply each value by the original
maximum "basic" speed value to establish the other five speed increments for
the ship log. ² Multiply each value by the previous equation result -
in "descending" order. Note that both of these methods will result in the same
six speed increments. The second method is faster but requires more
attention. |
